Graphene oxide modified low-efflorescence low-carbon cementing material and preparation method thereof
The invention belongs to the technical field of low-carbon cementing materials, and particularly relates to a graphene oxide modified low-saltpetering low-carbon cementing material and a preparation method thereof. The low-saltpetering low-carbon cementing material is prepared from the following raw materials in parts by weight: 180 to 250 parts of fly ash, 180 to 250 parts of mineral powder, 80 to 150 parts of liquid sodium silicate, 15 to 30 parts of sodium hydroxide, 130 to 180 parts of water, 1000 to 1500 parts of sand, 10 to 15 parts of graphene oxide and 1 to 5 parts of silane coupling agent. Meanwhile, the invention provides a specific preparation method. The graphene oxide is modified by the silane coupling agent, and the modified graphene oxide is grafted to the surface of the mineral powder and is matched with other components, so that the problems of serious saltpetering and poor mechanical property of a low-carbon cementing material are solved.
本发明属于低碳胶凝材料技术领域，特别涉及一种氧化石墨烯改性的低泛碱低碳胶凝材料及其制备方法。该低泛碱低碳胶凝材料由以下重量份的原料组成：粉煤灰180～250份、矿粉180～250份、液态硅酸钠80～150份、氢氧化钠15～30份、水130～180份、砂1000～1500份、氧化石墨烯10～15份、硅烷偶联剂1～5份；同时本发明提供了具体的制备方法。本发明对氧化石墨烯通过硅烷偶联剂改性同时将改性的氧化石墨烯接枝到矿粉表面，并与其他组份配合，解决了低碳胶凝材料泛碱严重、力学性能差的问题。
